METAL-PLAINING MACHINE.

Application fil d February 7, 1906. fierial No. 299,905-

To all whom it may concern:

Beit known that I, CORNELIUS OpHARLEY,

a citizen of the United States of America, and

a resident of S ringfield, in the county' of Hampden and tate ofMassachusettsyhave invented certain new and useful Improvements in Metal-Planing Machines, of which the following is a full, clear, and exact description.

This invention relates to improvements in planing-machines for metal, and is particularly applicable on a planing-machine of the general description set forth in Letters Patent of the United States granted to me and another, dated December 19, 1905, No. 807,740. i

The particular object of this invention is to provide equipments for the planing-machine whereby several tools or cutters may simultaneously operate to make cuts one in advance of the other and operable at the same time on one or more surfaces of a piece to be planed at each forward pass or run of the piece carried on the reciprocatory carria e relatively to the tools, to the end of greatly multiplying the capacity of the planing-machine and so that the planing of different pieces of work may be performed in only a fraction of'the time usually heretofore required.

Another object of the invention is to pro-' vide new tool-holders and equipments for the planing-machine and means for "mounting the same on the feed-head, whereby the holder is adapted for the reception of pla n ing tools or cutters which are equally well adapted on each passage of the work'fo'r mak ing planing cuts on a vertical or a horizontal" face of the work to be finished. v

The invention consists in the constructions of parts and the combination and arrange ment of parts, all substantially as hereinaf injuring the latter. I I

Two tool-holders D are shownas' c'arried Fig. 2 is a Fig. 4 is a front perspective Patented'Nov. 27,1906 I view of one of the disk-shaped planingtools or cutters; "Fig. 5 is a rearperspective View of the same. similar to the tool-carrying portion on Fig. 2, but showing an increased number of" disk Fig. 6 is a frontview somewhat tools. Fig. 7 is a view similar to Fig. 3 and illustrating capabilities for holding tools for horizontal surface planing, as wellas planing on a vertical surface.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents the tool feedhead of a planing machine, the same being understood as having ltslocatlonabeve the f' 'reciprocatory' carriage of the pl1an1ng-1na- ChlIlG, a portion of which carriage is repr'e sented atB, and it is common to, provide more than'one of the tool-carrying feed-headSl Afor'planing-inachines' v I V The meansfor im artingthe feed move ments vertically and orizontally to tfhfeed-f head Will not'be here illustrated or described,"

as the same involves no novelty.

The feed-head comprise'sa plate or block a? locatecl'between separated cheeks b b ofthe head and hung thereto'on the piVot bolt'd', such part beingbacked up againstandrejsist'ed by-the face of the head as the carriage and'w'ork run forwardly; but thes'aid plate or blockc is free to swing as represented inthe ,dottedlines,'Fig. 2, when the carriage'lias'its" reverse movement, so the returning piece of' worksuch, for instance, as represented at sc -"0n the carriage may pass'freely cutting-points of the planing-tools wi't'hc'jut by ea'ch feed-head A, the same'being mounted on the aforementioned pivotally hung" block or plate a,- and each tool-holder is" confinement thereon or 'therein of a'pluralit' i of the disk cutters or planing-tools f, and one of the tool-holders will nowbe fully described,

The tool-holder comprises a vertical shank equipped with means-for'the reception and,

10, having horizontal "slots 12' 12, 1, through the same from front to rearfjand i through which Sets the confining boltsl3,"

having the enlarged heads, passto engag'e The ,shanlc" at its extremity which depends below the headto a position Suitably adj'acen't'the, car-'1' ments into the block or plate a.

The positioning of one of the disks in a plane facewise offset from that of the other may be accomplished by letting one disk tool set fully against the base of its socket, while by a shim 38 the other tool-disk in the same holder is held in a relatively slightly outward position; but of course for horizontal surface planing the intermittent cross-feed of the machine would be employed instead of the vertical feed required between the passes of the work undergoing vertical surface planing. The disk cutters may be reground repeatedly on tangential or radial lines until much of their outer portions are used up.

I claim 1. A tool-holder comprising a bar portion, a plurality of disk-shaped cutters of varying diameter having angular recesses in their edge portions, one side of each recess, extending to the disk periphery, defining the cutting portion of the tool, said disks being arranged on said holder with the cuttingpoint of one extended farther beyond the edge of the holder than that of another, clamping-bolts, the shanks of which pass through the cutter-disks with thread engagements into the bar, and which by their heads bind on the front faces of the disks, and clamps mounted on the holder and having confining-bearings against the faces of the disks laterally of the points of bearing of the heads of said clamping-bolts.

2. A tool-holder comprising a bar portion having within its face a plurality of substantially circular sockets the sides of which open at one edge of the bar, a plurality of diskshaped cutters having angular recesses in their edge portions, one side of each recess,
